LEM- lgineer, a subject of the Kingof Great Britain and Ireland, residing at Windsor, Alexandra street, Drum'inoyne, :in the State yof New South Wales, Commonwealth ot Australia, have invented new and useful Im proved Fountain or Self-Feeding Pens, of which the following is a specification. v

This invention appertains to pens having a selfv contained reservoir'and has' been devised tol edcct improvements in the same wherein the lluidlreservoiris separate andremovable from't-heA pen Acasing orhandle,

the supply of Huid from lsuch ;reseifvQI.' and recharged and, moreover, ofsuchi-'construcl tially of V'an inkreservoir'having terminal tion that the casing jointsjof the pen aremaintain'ed fluid tight. l'

According to this inveii fountain or self feeding pen`v consists essennecks closed bycaps of puncturable material said reservoir' adapted to be inserted within the 'tubular casing or handle of the v pen and the-, ends taking between tubular piercing valves `one=positioned inthe handle end being lnon-return'. and communicating with the atmosphere land the other at the writing end controlling the supply of fluid to the pen. r

The non-return airvalve- 1s spring con'- trolled so that when in the horizontal posi tion the same is closed to prevent leakage and the fluid valve passage controlled by a partially rotatable capwhereby the flow of ink may be regulated and cut olf.

In the preferred construction the casing of the pen is slotted longitudinally at diainetrically opposite points and the reservoir constructed of glass whereby the fluid is visualized, and, further the writing end of the pen socketed to receive either an ordinary writing pen or nibor a ruling or drafting en. p Referring to the accompanying drawings depicting a fountain or self feeding pen constructed in accordance with this invention4 A-A and B-B respectively (Fig. 2). Fig. e 5 a partial perspective. view of a fountain drafting pen. Fig. 6 a longitudinal section thereof. Fig. 7 across section on line C-C tioli an improved Fi .valve seating. Fig. 8 a

g. 3). showing 'simi ar view on ine C-'C (Fig. 3)- of the valve. Fig. 9, is a perspective view of the removable ink reservoir.

The handle end 10 of the tubular cylin-A drical casing 11 of the pen is internally threaded to receive centrally apertured flanged plug 12 having screwed into its flange 13 similarly apertured Socket 14 through-which passes the stem 15 of valve casing 16 communicating through a terminal aperture with the atmosphere as shown.

The forward end 17 of the valvular passage 18 is enlarged and provided with a dished 'seating 19 for spherical valve 2O supported by Afine coil spring 21 bearingfthereon and upon the end of tubular conical ended plug 22 screwed into said enlarged valvular passage. lhis coil spring 21 is adapted to impart sutlicient pressure to the spherical valve Ato maintain same in its seating when the pen is in the horizontal position andthereby prevent leakage of the Huid through the valve.

One of. the terminal capped necks 23 of Y the cylindrical glass fluid reservoir 24 is pierced by the conical ended plug 22 the packing ring 26 beingprovided intermediate o f said end 23 and the forward end of the air valve casing 16 whereby the fluid is prevented from leakin into the annular space 27 between the tubu ar reservoir and the pen casin 11. For the purpose of maintaining ane ective joint with said packing ring 26 and securing the reservoir imposition, the

valve casing 16 is tensioned by spring 28 coiled about the stem of same and bearing against the bottom of socket 14 and acollar 29 provided on said casing 16. The other terminal capped neck 23 of the reservoir 24 is pierced by conical end 30 of the tube ,31 screwed into the tapered and reduced forward end 32 of the casing 11. The tube 31 communicates with the reservoir through olfset passage 33 in the end 30, its other end 34 enlarged and cone ended as shown being also provided with a terminal offset passage 35 controlled by valve 36 capping and provided with seating 37 for said end 34. The valve 36 is provided withofset passage 38 and has socketed ends 39 and 40 into the former of.. which fits the pen socket 41 the latter fitting over collar 42 on the enlar ed end 34 of tube 31 being externally threa ed to take.V in screwed end 43 of double ended and centrally apertured socket 44 the other end 45 of which has ta red recess ada'fted to rotate on tapered en 32 of the casmg.`

To regulate and also to prevent the movement of socket 44 when regulated, a stopl pin 46 is atlixed in the tapered end 32 of the casingl 11 operatingjn slot 47 inthe socket 44.and taking in teeth 48 in plate 49 alfxed to said socket 44 marked to indicate .the position of the valve. For maintaining the conical end 34 of the tube 31. effectively in `its seating 37 and prevent leakage of the fluida coil spring 50 takes about the tube 31 as shown andbears upon colla-r 42 provided thereon. A' packing ring 51 is provided in the forward end of the pen casing 11. for the same purpose as the ring 17. In

order to conduct the lluid from the te inal valvular passage to the point of a ruling or v air and fluid valvular passages are placed in lcommunication with the fluid (see Figs. 3 'and 4). The penis now ready for use it only being necessaryto open thel valve 37 to permit the passage of fluid to the pen nib or ruling pen. To `recharge the pen the plug 12 is unscrewed thereby removing the cone -ended plug 22 from engagement with the capped end 23 of the reservoir which may then be withdrawn.

What I claim and desire to secure -by Letters Patent is 1. A fountain pen'comprising a barrel, a removable reservoir having puncturable ends located within the barrel, an ink feed at one end of the barrel and an air feed at the other end of the barrel, both feeds having pointed ends extending within the. removable reservoir, the normal distance between the pointed ends being less than the length of the reservoir.

2. A fountain pen comprising a barrel with longitudinal visual slots therein, a removable reservoir having puncturable ends eo'y passage at the other end of the barrel, both of saidv feeds having pointed ends extend-k ing within the puncturable ends of the removable reservoir, the normal distance between the pointed vends being less than the length of the reservoir.

4. A fountain pen, comprising a barrel, a removable reservoir. having puncturable ends located within the barrel, a valve controlled air feed at one endof the barrel, a valvular ink feed havinga terminal offset passage at the other end of the barrel, both of said'A feeds having pointed ends extending within the puncturable ends of theremovable reservoir, the normal distance between the pointed ends .being less than the length of` the reservoir, and a rotatable valvular capdto regulate the flow-through the ink fee 1 5. A fountain pen comprising a barrel, a removable reservoir having 'puncturable ends located within the barrel, a valve controlled air feed at one end of the barrel, a valvular inl: feed having a terminal offset passage at the other end of the barrel, both of said feeds having lpointed ends extending within the puncturable ends of the removable reservoir, the normal distance between the pointed ends being less than the length of the reservoir, a rotatable valvular cap to regulate the flow through'the ink feed, and means for indicating the position of the valvular cap with relation to the ink feed.

In witness whereof I have hereunto affixed my signaturev in the presence of two subscribing witnesses.
